Product Describtion
HN-5508 is a two-component epoxy potting compound designed for
room-temperature or low-temperature curing. With low viscosity,
extended work time, and excellent fluidity, it penetrates easily
into product gaps. After curing, it forms a bubble-free, smooth,
and glossy surface with high hardness. The cured material exhibits
outstanding resistance to acids, alkalis, moisture, and aging,
along with superior electrical insulation, voltage resistance, and
bonding strength. Ideal for electronic components requiring
encapsulation, insulation, and environmental protection.
Product Advantage
✅ Reliable Protection: Shields against moisture, vibration, and thermal stress.
✅ Versatile: Adapts to diverse electronic and industrial applications.
✅ Cost-Effective: Long pot life reduces waste during processing.
